The casing 9 is supported in the bracket ring 16, which has on arm 17 longitudinally adjusted, and also capable of being turned to adjusted position in the tubular bracket arm 18. The arm l8 has an angular-1y disposed. sleeve 19 that is fitted to e support. as one of the side bars of an automobile Wind shield (not shown), and the parts 16, l7, 18 thus form a laterally extending support for the lamp.

Both the horizontal. and the vertical or tilting movement of the lamp are accomplished from the same shalt 20,,whieh is arranged transversely of the casing 9, passing therethrough and the shaft is supported in Merings 21 in the wall of the casing and by an intennediatebeuring 521 in the interior of the casing. A comparatively wide bevelgeer 22 is fixed on shaft 20 within the casing 9, and engages normally with a complementary rack ring 23 on the lower end of the swivel head 7. Within the swivel head is journaled a vertically disposed stub shaft A on which the bevel pinion 25 is fixed, and with this bevel pinion the gear is also normally engaged. At its upper end the stub shalt has a fixed rack wheel 26 located in the groove in the rib of the base plate and in engagement with the arcuute rack 5 on the grooved rib.

The operating shaft 20 is actuated through the flexible shaft section 27 from the hand wheel 28 and its shaft- 29. the latter being journaled in bearings as 30 and coupled in suitable manner to the flexible shaft section. The flexible shaft section may be of suitable length, and is designed to permit attachment of the shaft bearings 30 in location in order that the hand wheel 28 may be positioned "for ready access by the automobile driver. regardless of the point of attachment of the lamp bracket to the windsl'iield. Thus the lamp may be attached to the windshield. and the hand wheel located near the lump, as in Figures 1 and 2, or the lamp may be provided with a longer flexible shaftsertion to permit attachment of the band wheel nearer the driver of the car.

For turning the lamp the shaft '20. and its wheel 22,10 engagement with wheel 2:: and rack ring, 23, are manipulated from the band wheel 28. For tilting the lamp. the shaft "20 is shiftabie longitudinally in order that the wheel 22 may he released from wheel 25 and ring 23, and the shaft may be shifted by a pull on the band wheel 28.

On the shaft 20 between the intermediate bearing 21 and the casing are interposed clutch members including" a loose bevel pinion 31, shiltable with the sl'm'l t 30 that is adapted to be pulled into engagement with rename teeth 32 of the bottom or" the casing end also with raclt ring 23 oil the swivel heed.

loose pinion 31 by its engagement with the fixed teeth and reel: ring 23 holdsthe latter, and the swivel head against turning in a horizontal plane when the lamp is tilted. Between the loose pinion and the intermediate bearin; are a tight, smaller pinion 33 and a spring 34., the latter coiled shout shaft 20, and adapted normally to hold the shaft 20, wheel or pinion 33, and pinion 31, in normal position as in Figure 2. When the shaft 20 is pulled to the right in Figure 2, against tension of spring 3i, the pinion 31 first locks the swivel head against turning, while the pinion l-l is caused to clutch the larger rack wheel 25 of stud shaft Now as the hand whee 238 is turned the stud shaft 24 revolved, and wil it the reek wheel and smaller rock wheel As the latter is in engagement with the reel; 5 out the lamp-base, the lamp base and lamp ms. t be tilted to positions between the extreme positions indicated by dotted lines in Fig ure 4. llhen the lamp has been tilted to roperly adjusted position, the hand wheel IS released, the spring 3% returns the shaft 20 to normal position, and ti e gear 22 engages the rack ring 23 and rack wheel to hold the latter, thus holding the lamp as desired.

By this means the lamp may be turned horizontally on its swivel joint, and tilted in a vertical plane, to a variety of uses.

In some instances the lamp maybe used as n portable lamp and for this purpose the reflector and electric bulb are detach ably secured within the nut 37 fixed at the rear of the lamp by threading on the head 38 of the bulb. .A. comparatively long Wire or cord 39 is connected with the electric light and. wrapped around :2. shell 40 within the lamp casing. one end of the wire of course being connected with a source of supply. By unscrewing" the nut 37 the bulb, reflector, the, may be detached from the lamp casing and used as a portable lamp, the wire 39' being unwound from its shell to permit carrying the lam p away from its casing.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:-

17 The combination a. dirigible lamp, with its fixed base plate and an ercuate rack-rib thereon, ot a casing, a head in said casing and grooved to receive said rib, means for guiding said rib, a stud shaft in the head and a. rack wheel thereon engaging the rack rib, and means for turning said shaft to tilt the lamp.

2. The combination in a dirigible lamp, with its base plate and an. arcuste reek-rib thereon, of a casing, a. head in said casing having a transverse groove to receive said rib. grooved flanges on the head and complcmentury guide flanges on said plate, a

emme stud shaft in the head having a' rack Wheel ing said shaft.

The combination in a dii'igibie lamp with a (resin and a swiveled heed ther in having a' me ring, of a shifmble" shafts, e toothed portion in the casing, and a loose gear on said shaft adapted to engage said ring and toothed portion to look said heed, a stud shaft in the head and means thereon for tiltin E'ne hinge rack wheel on said shaft, an a pinion on the shiftehie' shaft to engage said rack Wheel, and brake means for retaining the lamp.

5. The eoinbinetion in o. dirigibie lamp with a casing, of a swiveied heed huving'e reek ring, a shiftable shaft having speoed gear wheels adapted to selectively enge e said reek ring, a loose gear wheel on said shaft, a stud shaft in the head having conneotions therefrom to tilt the lamp, a rack Wheel on the stud shaft adapted for selee five engagement bysaid loose gear or one of said spaoed gears, and a; toothed face in @he casing adapted to oo-eot, with the other spaced gear, whereby the shifmbie shaft may be moved iongitudinaily and turned for the purpose described. 1
